Default After Market Fog Lights keep blowing fuse!

Hi,
The stock fog lights on my 2001 xj were cracked so i bought some 55 watt lights at walart. I cut the connector off the stock light and put it on the new light. When i go to turn them on (using the stock fog light switch) the 15A mini fuse under the hood pops......What am i doing wrong?? I dont know much about electrical stuff so be easy on me. Thanks!!

Too much current for the tiny wires in the XJ's harness. I highly recommend you run your own wiring harness. It's not that hard, just make sure you put an in-line fuse on the positive lead to the battery, and use a relay.

Thanks for the quick response! The lights came with a wiring harness and inline 15A fuse but no relay. The stock wires seem to be the same size as the new wiring harness so i am still curious why it doesn't work. I would like to keep the stock switch. Thanks

Besides being crack, did they work.
Maybe it has nothing to do with your installation,check the wiring.

The old ones always worked until they cracked and got exposed to the elements. The new ones worked the first time i tested them for about a minute. Now every time i hit the switch it blows the fuse.

make sure there is no exsposed wireing touching any metal first off,then check the wattage of the stock bulbs,i know for a fact 55watt bulbs will need a 30amp fuse

Sounds like you have a short somewhere in the system. That would cause it to keep popping fuses. If you don't want to try to hunt down the short you can just rewire it with a 30 amp relay as others have mentioned. Running a new wire harness would be a lot easier then trying to find the short in the old one.

I agree with what everyone else is writing. Rewire it so that the appropriate fuse can be used. Do NOT just pop a 30 amp fuse in the factory location. The wire may be weak somewhere and instead of blowing the fuse, you can heat up the wire and cause a fire. Good luck.

X2
The original is 55w,which is a 10 amp load (for 2).

Maybe there is a pinch wire, when you mounted the lights.
Take them out, and turn them on and see what happens

You have a short to ground somewhere. The factory harness will support 55W lights. As stated before, check your wiring.
